Seems to me that CodeIgniter to Django is a much bigger leap than PHP to Python. Or even in general, unless you're dealing with a language that has a fundamentally different approach, frameworks constitute a much bigger learning curve. Especially if you're coming from a simple, lightweight framework like CodeIgniter to Django. Much of what the author describes would also apply if you go from CodeIgnitor to Symfony, even though it's still PHP.
